Casper, WY – Negotiations over a contract to start Northwest Airlines service from Casper to Minneapolis are progressing well. That's according to Casper Area Economic Development Alliance President Chris Manegold. It took Northwest several weeks to send CAEDA a draft contract, and the Casper Airport Manager says it's more more likely they'll have to wait until next spring to start the service. Manegold still is shooting for an October 4th start date. He believes there's still time between his group and Northwest to negotiate a contract and start service this fall. Manegold says a start up date of next spring is the fall-back option.
